Will at CT scan or MRI pick up a parasite?

Will at CT scan or MRI pick up a parasite?

In many instances: Usually we see the results of the body's reaction to the parasite, rather than the parasite itself. Parasites such as cysticercosis can deposit material which en sites the body to react - for instance in the brain. In other situations a byproduct of infection such as an amoebic abscess in the liver can be identified. Virtually every organ system can show the result of parasitic infection. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Is an IV required for a CT scan or MRI due to migraines?

Is an IV required for a CT scan or MRI due to migraines?

IV and imaging: The CT or MRI is much more sensitive for certain abnormalities that cause headaches if the test is done with IV contrast. Although it is not required. An IV helps make the study more useful to your physician. ...Read more

Abdomen pain and suspicion, should I get a CT scan or mri?

Abdomen pain and suspicion, should I get a CT scan or mri?

Maybe: First exam should be a simple abdomen xray. If doctor thinks the gallbladder could be diseased, then an ultrasound is best.

Most other ailments best served with a ct scan. Mri can help if a patient can't have ct contrast because of prior reaction or poor functioning kidneys.

Mri scans take longer, cost more, and not readily available as ct scans. ...Read more

Which has less side effects on body especially brain, CT scan or mri?

Both very safe: However, MRI is likely safer because it does not use ionizing radiation like ct.

Mri is essentially a very fancy radio, and ct is a very fancy x-ray machine, taking images from multiple directions to make a picture.

Contrast agents, usually injected into a vein as part of both MRI and ct, have risks as well, however they are very low, well known and easily avoided or managed. ...Read more

Which is better at evaluating complex renal cysts in children - CT scan or mri? Is the bosniak scale used in children?

Which is better at evaluating complex renal cysts in children - CT scan or mri? Is the bosniak scale used in children?

Reasonable F/U...: Either one should be sufficient for evaluation after suspecting cystic lesion in kidneys of children, which can be categorized with bosniak system. After that, no further ct or MRI is needed but annual renal us in 1 yr for 1-2 times. If stable and asymptomatic with normal us, further study is usually unnecessary. Of course, beware of unwanted radiation to the children. ...Read more

Will a CT scan or MRI show coronary arteries without the dye?

Will a CT scan or MRI show coronary arteries without the dye?

Not well: A contrast enhanced exam is necessary to assess the coronary arteries in a meaningful way in young patients. Cardiologists use contrast for catheterization, but noninvasive coronary angiography with contrast is preferable. Read more about ct scans and contrast here:

What's better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Why worried?: Why are you worried? Do you have symptoms or abnormal labs?

If the ct was normal and used a specific pancreas protocol, then an MRI of the pan creas may be the best next test. Since it does not use radiation, there is little risk for you. ...Read more

What's better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.

CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and CEA can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...Read more

Can a CT scan or MRI of the lumbar could show a differance if my grama was very constipated she said it was causin lots of presure pshin on the l/bone?

Can a CT scan or MRI of the lumbar could show a differance if my grama was very constipated she said it was causin lots of presure pshin on the l/bone?

Not the MRI, maybe CT: The lumbar MRI will not image the bowel. It will show problems involving or surrounding the spine. If she is having pain from constipation, she may not need any imaging. If there is a questions, her doctor may decide to start with an x-ray and may only do a cat scan if it's really needed. ...Read more

How do a CT scan and a MRI differ?

How is a CT scan and an MRI different?

MRI vs CT: The main difference is that CT uses ionizing radiation and MRI uses radiowaves (non-ionizing radiation). It is the ionizing radiation that causes injury to the DNA and potential to develop a cancer down the road.

In general, CT is good at looking a differences in radiation absorption (x-ray density). MRI is good at looking at subtle chemical differences (water and fat) in tissues. ...Read more

In what aspects CT scan is better than MRI scan?

Looking at bone: The CT scan is better than MRI in detecting bone fractures or pathologies involving the bone. MRI is better at distinguishing between soft tissues. CT scan is also faster & quieter than MRI. However, the CT scan uses radiation & there has been an explosion of radiation-related conditions in recent years. Each modality measures different things. So ask your doctor if the test is needed or not. GL. ...Read more

Is an MRI better than a CT scan for diagnosing back pain?

Is an MRI better than a CT scan for diagnosing back pain?

MRI vs CT: A ct myelogram (where contrast is injected to highlight discs, nerves, etc) is comparable to a back mri. Orthopedic surgeons & neurologists have their preference. Both will do a thorough exam before recommending an imaging study. Conservative treatment with analgesics, muscle relaxers, physical therapy may be enough at first. ...Read more

Is it possible to miss a stroke on CT scan? Is MRI always done?

Not always: Ct is not good for stroke in the first 6-24 hrs, especially in small strokes. It is always done however because it is more accessible, is cheaper, and because it is necessary to exclude a brain bleed. Mri is far superior in stroke detection, assuming the patient has no contraindications, like a pacemaker. ...Read more

Missed Diagnosis: Yes, it is possible that a diagnosis was missed on your x-ray, ct or mri. Radiologists are just like all other humans and can, unfortunately, occasionally make mistakes. If there is concern, consider asking your doctor to discuss the examination personally with the radiologist who interpreted the exam and then to discuss those results with you. ...Read more

Mri (Definition)

Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
